2878 General Description
These quad Darlington arrays are designed to serve as interface between low-level logic and peripheral power devices such as sole-noids, motors, incandescent displays, heaters, and similar loads of up to 320 W per channel. Both integrated circuits include transient-suppres- sion diodes that enable usewith inductive loads. The input logic is compatible with most TTL, DTL, LSTTL, and 5 V CMOS logic.
Type UDN2878W and UDN2879W 4 A arrays are identical excep for output-voltage ratings. The former is rated for operation to 50 V(35 V sustaining), while the latter has a minimum output breakdown rating of 80 V (50 V sustaining). The lower-cost UDN2879W-2 is recommended for applications requiring load currents of 3 A or less. These less expensive devices are identical to the basic parts except for the maximum allowable load-current rating.
For maximum power-handling capability, all drivers are supplied in a 12-pin single in-line power-tab package. The tab needs no insula-tion. External heat sinks are usually required for proper operation of these devices.
